An optical method using the Kerr effect is reported for the measurement of high voltage transient pulses with benzonitrile, acrylonitrile, propionitrile, butyronitrile and m-nitrotoluene for the first time along with nitrobenzene and acetone that are well known. These investigations have been performed using high voltage pulse fields ranging from 5 x 105 vm"1 to 107 vm-1. The experimentally measured values of the electric field from the Kerr signals are found to be in excellent agreement with applied field. © 1995 The Japan Society of Applied Physics.

The electro optical Kerr coefficients of binary liquid mixtures, comprising of aprotic-aprotic molecules only, are measured over the temperature range of 286 K to 315 K. To with in experimental errors, the logarithm of Kerr coefficient can be expressed as Van't Hoff type expression to the reciprocal of temperature. Information on the interaction energy between the constituents of the binary mixtures is thereby obtained. It is found that the interaction energy in aromatic ketone-aliphatic nitrile binary mixtures is comparatively higher than in the binary mixtures with aliphatic ketone-aliphatic nitriles, aromatic ketone-aromatic nitrile and aromatic ketone-aliphatic ketones components. This is attributed to the dipole-dipole interaction existing between the components of the binary mixtures.The electro optical Kerr coefficients of binary liquid mixtures, comprising of aprotic-aprotic molecules only, are measured over the temperature range of 286 K to 315 K.
